I chose to operate the shutter walls with stepper motors, and eventually worked out a way to attach them directly to one of the louvres within the linkage of each of the vertical shutter walls. However, this left me with the problem of how to keep the stepper motor still and secure, without spoiling the aesthetic of the pavilion.

To solve this I created a wooden enclosure for the motor to sit in, which would be attached to the roof of the pavilion. The enclosure was based on a scaled-down version of the pavilion itself. The gaps left between the layers of the enclosure allow air to reach and cool the motor.
